Abstract
The invention relates to the use of a first coding or decoding rule for a normal operation and of a second coding or decoding rule for a particular operation. Said invention provides the opportunity for speedily transmitting data between different satellite devices arranged in a motor vehicle and an evaluation unit arranged, for example in the central part thereof, even when the data bus (31, 32) of a transmission channel CAN (3) is externally short circuited, for example by a traffic accident, i.e. the data bus BUS L (32) and the data bus BUS H (31) are connected to earth (GND) or to a battery (Vbat). The invention can be used, in particular for protecting passengers.
